According to the historical background and current situation along with the important influence of establishing forest for killing snails, this paper sets forth the difference between beach land forest for killing snails and other forest categories. Besides its special function, the beach land forest for killing snails has its own geographical conditions, typical composition, particular silvicultural technology and stand structure. Based on the rules of beach land forest with intensive management, short rotation and comprehensive development in large scale, it is considered that beach land forest should be regarded as a new forest category in forestry. Therefore, in the middle and lower reaches of the Yangtze River the forest categories should be divided into four types, which are the beach land forest for killing snails, shelter forest, production forest and recreation forest. Finally, some constructive suggestions have been put forward for how to speed up the development of the beach land forest for killing snails and enhance the social effect of killing snails and preventing disease caused by snails.
